Neurophysiologic responses to the first minute of songs predicted hits with an 82% success rate, indicating that the early part of a song plays a crucial role in determining its popularity.

This week, a team of over 1,000 scientists from around the globe released to the public the first batch of data collected with the Dark Energy Spectroscopy Instrument (DESI), a telescope that cosmologists hope will help answer open questions on the nature of dark energy and the evolution of the Universe [1– 3]. “The telescope works better than we ever imagined,” says Michael Levi, a cosmologist at Lawrence Berkeley National Laboratory (LBNL), California, and the director of the DESI Collaboration. “We are ready to have everybody look at this [initial] data release and see what they can do with it.”

The goal of the five-year-long DESI survey is to map the Universe deeper in time and higher in detail than any previous telescope (see Feature: Entering a New Era of Dark Energy Cosmology). “We want to go way beyond what was done before and really be able to see the evolution of dark energy over the history of the Universe,” says Nathalie Palanque-Delabrouille, a cosmologist at LBNL and one of the spokespeople for the DESI Collaboration. To see that evolution, the survey plans to pinpoint the locations of over 40 million galaxies. The key to filling in the cosmic map is the use of robotic technology that automatically alters the placements of light-collecting fibers so that they can retrieve spectroscopic information from targeted bright spots in the sky. The spectral measurements provide information on what an object is and how fast it is moving away from us, which is needed to estimate its distance.

The robotic technology used to target objects had never been tried before, so it was not always clear that DESI would perform as expected, Levi says. But he and other team members have been pleasantly surprised by how smoothly the machine has operated. “DESI has preserved every photon that the Universe gave us,” he says.

Warning of the catastrophic collapse of a neutron star could come in the form of potentially detectable radio bursts in the 10–20 gigahertz range.

Microsoft Azure Bastion and Azure Container Registry have each been found to have one potentially “dangerous” security flaw that, if taken advantage of, may have resulted in a cross-site scripting (XSS) attack being carried out on the affected service. XSS attacks take occur when threat actors insert arbitrary code into a website that would otherwise be trusted. This code is then run each time visitors who are not aware of the attack visit the website.

Both of the vulnerabilities that Orca found take use of a vulnerability in the postMessage iframe, which makes it possible for Window objects to communicate with one another across domains. The vulnerabilities allowed for illegal access to the victim’s session inside the compromised Azure service iframe. This may result in serious repercussions, such as unauthorized data access, unauthorized alterations, and interruption of the Azure services iframes, among other things. This meant that the vulnerability could be exploited to embed endpoints into remote servers by utilizing the iframe element. This would eventually result in the execution of malicious JavaScript code, which would compromise sensitive data.

However, in order to take advantage of these vulnerabilities, a threat actor would first need to undertake reconnaissance on various Azure services in order to identify vulnerable endpoints contained inside the Azure interface. These endpoints may be missing X-Frame-Options headers or have Content Security Policies (CSPs) that are inadequate.

There’s some potentially big news on the hunt for dark matter. Astronomers may have a handle on what makes this mysterious cosmic stuff: strange particles called “axions.”

Rather than search directly for axions, however, a multinational team of researchers led by Keir Rogers from the University of Toronto looked for something else. They focused on the “clumpiness” of the Universe and found that cosmic matter is more evenly distributed than expected.

So, what role do axions play here? Quantum mechanics explains these ultra-light particles as “fuzzy” because they exhibit wave-like behavior. It turns out their wavelengths can be bigger than entire galaxies. Apparently, that fuzziness plays a role in smoothing out the Universe by influencing the formation and distribution of dark matter. If that’s true, then it goes a long way toward explaining why the matter in the cosmos is more evenly spread out. It implies that axions play a part in the distribution of matter in the cosmos.

After that, those who have been waiting more than a decade for their ride aboard Virgin Galactic’s rocket-powered space plane are expected to get their chance. The company said the first of those flights will begin in early August, with monthly flights following that.

“This next exciting chapter for Virgin Galactic has been driven by innovation, determination and a commitment to delivering an unparalleled and truly transformative customer experience,” CEO Michael Colglazier said in a statement.

Virgin Galactic has been working for years to send paying passengers on short space trips and in 2021 finally won the federal government’s approval. The company completed its final test fight in May.

NASA will partner with SpaceX to make Starship space stations. This is part of NASA partnering with seven U.S. companies to make advanced space capabilities. SpaceX is collaborating with NASA on an integrated low Earth orbit architecture to provide a growing portfolio of technology with near-term Dragon evolution and concurrent Starship development. This architecture includes Starship as a transportation and in-space low-Earth orbit destination element supported by Super Heavy, Dragon, and Starlink, and constituent capabilities including crew and cargo transportation, communications, and operational and ground support.

Making Giant Space Stations Using SpaceX Starships

Each Starship has more than the volume of the International Space Station. They are also similar in size to the external fuel tank of the old Space Shuttle. There were many space station proposals based upon the external fuel tank of the Space Station. It will be easier to build with SpaceX Starships. The steel construction the SpaceX Starship makes them easy to weld, cut and modify. The SpaceX Starships will start being able to support astronauts.
